Title: Shading correction system
Inventor: MITA YOSHINOBU
IPC: H04N1/40
Filed: 1984-07-31
Abstract: PURPOSE:To eliminate an error in shading correction due to the dirt, flaw, dust, etc., of a white calibration plate by correcting the shading of image data on plural picture elements on the basis of the means value of shading correction data read out of the white calibration plate as to plural picture elements. CONSTITUTION:A RAM5 is placed in read mode with a control signal J and image data A obtained by reading the white calibration plate by a solid-state image pickup element is inputted to an adder 1 in synchronism with an image transfer clock F. The adder 1 inputs the output C of a data latch circuit 2 and supplies its addition output B to a data latch circuit 2 and a shading data RAM5. Further, the data latch 2 is cleared every time a main scan synchronizing signal G is applied. The mean value of plural picture elements of image data A are stored in the RAM5 successively as shading data in the form of the addition output B. Then, read image data A of the original is supplied to a shading correcting circuit 6 and a data D for shading correction read out of the RAM5 in read state with the control signal J is also supplied to the correcting circuit 6.

Filed: 1989-06-22
Abstract: PURPOSE:To expand reproducing band width to a low-pass area side without changing the entire length of an acoustic coupler by forming the acoustic coupler in double structure in which the cross-sectional area of the acoustic coupler is formed wider at a joining side with a speaker and narrower at an aperture terminal side. CONSTITUTION:The acoustic coupler extending successively from either side the front plane or the back plane of the speaker unit and whose aperture 8 is opened to a sound field space is arranged, and the acoustic coupler is formed in the double structure that the cross-sectional area is formed wider at the joining side 6 of the speaker unit and narrower at an aperture terminal side 7. Thereby, a frequency generating resonance phenomenon in the acoustic coupler can be reduced without changing the length of the acoustic coupler by increasing equivalent acoustic capacity in the acoustic coupler. Also, the frequency in which a 3/4-wavelength to decide the upper limit of a reproducing area becomes equal to the length of the acoustic coupler almost remains unchanged with the equivalent acoustic capacity, and the limitation of low sound reproduction is expanded, and also, the upper limit of the reproducing area almost remains unchanged, thereby, a speaker system in which the reproducing band width is expanded to the low-pass area can be obtained.

Abstract: PURPOSE: To easily open only an opening position by forming a cylindrical collar on a base part of a drum in such a manner that the tips of cutting teeth does not exceed a tip of the collar. CONSTITUTION: An opening-closing closure 1 is removably engaged with a drum 2 through the threads 3, 4. An inside of the opening-closing closure comprises the cutting teeth 5 for forming an opening on a wall 6 of a container near the center of a spout inside of the drum 2. Before the container is unsealed, a protective ring is engaged between the opening-closing closure 1 and the drum 2 for preventing the unsealing by mistake before use. A hard collar 8 which can be gripped by the fingers is formed coaxially with the opening-closing closure 1 and the drum. This collar 8 is formed in such a manner that a tip 9 of the collar 8 is projected to exceed the tips of the cutting teeth 5 even when the cutting teeth 5 are located on a position to form the opening.  The operation can be stably and conveniently performed by gripping the collar 8 by one hand when the opening-closing closure 5 is screwed by the other hand to form the opening on the container.

IPC: B63B43/14
Filed: 1984-07-30
Abstract: PURPOSE:To enable a ship to sail over a shallow-draft region by providing the middle parallel part of the ship with a shell part, which is made of flexible members and which can be folded into a plane having corrugations parallel to the ship's fore-and-aft direction, so that the shell part is expanded by filling it with air so as to give the ship the reserve buoyancy. CONSTITUTION:An air-tight buoyancy bag made of flexible members consisting of reinforced rubber film or the like is installed on the middle parallel shell part of a ship. When shrunk, the buoyancy bag can be folded in orders, to form a shell part 2 having corugations parallel to the ship's fore-and-aft direction, while, the bag is expanded by endosing air inside. When the ship sails over a shallow-draft region, reserve buoyancy can be obtained by expanding the buoyancy bag, thereby lessening the ship's draft or enabling her to sail over the region. When not in use, the buoyancy bag is folded into a plane having corrugations parallel to the ship's fore-and-aft direction, thereby preventing the hull resistance from increasing.
